Visão geral do uso de memória
O processador de rotas (RP) do Cisco ASR 1000 Series Aggregation Services Router tem RAM dinâmica síncrona (SDRAM), que fornece armazenamento para código, dados e pacotes. O RP oferece escalabilidade de memória de até 4 GB para ASR1000-RP1 e 16 GB para ASR1000-RP2.
Os Cisco ASR 1000 Series Aggregation Services Routers apresentam o software Cisco IOS XE como sua arquitetura de software. Baseado no software Cisco IOS, o software Cisco IOS XE é um sistema operacional modular construído em um kernel Linux no processador de rotas. O daemon IOS (IOSd) é executado como um processo padrão no nível do usuário no Linux e fornece o conjunto de recursos do Cisco IOS, que inclui protocolos de roteamento. Na inicialização, o IOSd recebe acesso a uma quantidade fixa de memória física no RP, geralmente 50% ou 1 GB em sistemas de 2 GB e 2 GB em sistemas de 4 GB. A operação dupla do IOS com chassi de 2/4 RU com 4 GB de memória principal para redundância de software consome 1 GB cada.
Para exibir informações sobre o tamanho da memória, software, hardware e versão da interface da Web, use o comando show version.

Para exibir o uso de memória para cada processo executado no Cisco IOS XE, use o processo do software da plataforma de monitor {fp|rp} {ative|standby}. Depois que a tela for exibida, você poderá digitar "shift + M" para classificar os processos exibidos com o uso de memória.
RES indica a memória física não trocada que um processo usa e SHR indica a quantidade de memória compartilhada usada por um processo. RES + SHR é a quantidade total de um processo, e %MEM indica o compartilhamento atualmente usado de memória física disponível para os processos.

Caso esta mensagem seja exibida quando você emitir o comando monitor platform software process no console, você precisará definir um tipo de terminal com o comando terminal terminal-type para se adequar a um, como VT100.
Router#monitor platform software process rp active
Terminal type 'network' unsupported for command
Change the terminal type with the 'terminal terminal-type' command.
Router#terminal terminal-type VT100
